The invention discloses a helicopter cockpit door locking mechanism, comprising an inner handle assembly, outer handle assembly, an upper lock box assembly and a lower lock box assembly disposed on acockpit door body, and an upper lock base assembly and a lower lock base assembly disposed on a cockpit door frame. The inner handle assembly and the outer handle assembly are connected by a pull rodassembly; the outer handle assembly and the lower lock box assembly are connected by a connecting rod assembly; the outer handle assembly and the upper lock box assembly are connected by a steel wirerope assembly; during locking, lock columns in the upper lock base assembly and the lower lock base assembly are clamped by latches in the upper lock box assembly and the lower lock box assembly, respectively; and a two-stage stop structure is adopted, so that a latch plate cannot reversely rotate, the clamping is reliable, and high-intensity helicopter flight requirement is met. During unlocking,the opening and the closing of the inner and outer handles do not interfere mutually, so that the performance is reliable, and the service life is long.
直升机驾驶舱门锁闭机构，包括设置在驾驶舱舱门主体上的内把手组件、外把手组件、上锁盒组件和下锁盒组件，以及设置在驾驶舱门框上的上锁座组件和下锁座组件，内把手组件与外把手组件之间由拉杆组件相连接，外把手组件与下锁盒组件之间由连杆组件相连接，外把手组件与上锁盒组件之间由钢丝绳组件相连接，锁闭时，上锁盒组件和下锁盒组件中的锁钩分别卡住上锁座组件和下锁座组件中的锁柱，且采用二级止动结构，锁钩板不会倒转，卡紧可靠，适合直升机高强度飞行要求。开锁时，内、外把手开闭互不干扰，性能可靠，使用寿命长。
